@MacBoy - Can you elaborate your problem a bit more ? Do you want to remove all white spaces or only the more than ones — gagan sharma, Jun 21 '16 at 09:10
@MacBoy - I tested stringByReplacingOccurrencesOfString is removing all white-spaces, for further investigation please share your code snippets or exact string you are modifying... — gagan sharma, Jun 21 '16 at 12:36

Easy Peasy, use this line:

NSString *TrimBase64String=[base64String stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

This should remove the white space characters that are at the begining or at the end only, not the one in the middle. – Larme Jun 21 '16 at 18:41

Use below lines of code to create NSString with Base64 Encoding to avoid white spaces and then post it:

NSString *strbase64 = [YourNSData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];

I tried many ways and finally found the cause of the problem is the character \r

\r = CR (Carriage Return) // Used as a new line character in Mac OS before X`

[yourBase64String stringByReplacingOccurrencesOfString:@"\r" withString:@""];
